Abstract: Optical switch comprising an input optical collimator having a first axis of collimation of an optical beam, two output optical collimators, one having a second axis and one having a third axis of collimation of an optical beam, and a device for the distribution of the optical beam directed along the said first collimation axis towards one of the said second and third axes of collimation of the optical beam. The said device comprises at least one reflector movable between a first and a second predetermined position, which provides an optical connecting path between the said input collimator and one of the said output collimators, in which each of the said first and second positions corresponds to the selection of one of the said output collimators.
